San Francisco , California -LRB- CNET -RRB- -- On Wednesday , Sony unveiled Move , its motion-sensitive controller .

A small device that looks like a microphone -- but with something on top of it that looks like a ping pong ball with an LED inside -- Move is Sony 's bid to gain control over the motion controller wars that are currently led by Nintendo , with its Wii controller , and which many think will be dominated by Microsoft and its Project Natal controller system .

To Sony , releasing the Move is an obvious move for the PlayStation , given it believes it started the motion controller era with its Eye Toy . Sony held its press conference during the Game Developers Conference here .

Now , the Move , which will be available this fall in a starter kit that begins at under $ 100 for a Move , a PlayStation eye camera and a game , is its attempt to jump ahead of Microsoft 's Natal and to begin winning over Wii users .

`` We like to think that the migration path between Wii households and PlayStation households is a natural path , '' said Peter Dille , Sony 's senior vice president for marketing and PlayStation .

Shuehei Yoshida , Sony 's president for worldwide studios , said Move will `` demonstrate that the motion controller for PS3 will be the solution for both casual and hard-core gamers alike '' and that the types of games Sony can create with it are `` amazingly diverse . ''

Among the types of games Move will work with include those that involve swords , bows and arrows , guns , punching and much more . The idea is that Move will provide players with a realistic and precise feeling of holding whatever kind of thing the game calls for , be it a sword or a gun .

Sony first talked about its new motion controller at E3 last year but did n't have a name or any kind of timing . Now , by unveiling the device 's name it can begin what Dille said will be the company 's biggest video game marketing effort of the year .

While Sony is expecting consumers to use Move with a range of brand-new games , the company also clearly thinks that it will enhance game play in existing titles . As such , it showed off how Move can be used to move characters around in its hit title , Little Big Planet .

Further , the controller comes with its own accessory , known as a sub-controller , which will accentuate what 's possible with Move . And later this year , the forthcoming game SOCOM 4 will incorporate both Move and the sub-controller .
